Crash in Compile::find_intrinsic

[Rémi Forax]

I've updated PHP.reboot to jdk7 b123 API.
All tests pass but one: test/testfibo.phpr

Step to reproduce:
download phpreboot from the SVN repo:
http://code.google.com/p/phpreboot/

run:
bin/phpr.sh test/testfibo.phpr

[forax at localhost phpreboot]$ bin/phpr.sh test/testfibo.phpr

I can reproduce the crash with the 64bits and 32bits server VMs.
